may have some influence on the body. After all the brain wave activity is divided into Alpha, Beta, Theta, and other wave frequencies.
That being said my initial experimentation precludes a human influence. My friend employs a Schumann generator and has in placed in the far rear left corner of his listening area. holding the generator I could simply extend the power cord and pass out of the room proper. I could hear, and so could the two others in the room (my host had consumed several glasses of a good wine and was, ah, slightly impaired in his physical abilities), the simply movement of the generator from one room divide into the other. Mind you, I was holding the unit in my left hand in doing so, so it should not have affected my hearing in any way.
Hence my conclusion that the effect was upon whether the room or the equipment but not the person.
In regards to other tweaks. I no longer color my discs. However I use a simple CD shaped disc to place upon my playing discs. The effect is often subtle but it is there. There is a simple explanation for it too: the absorption of scattered light.
I use that same disc, cut suitably, to line the bottom of the CD/DVD tray with good results. Again, examining the principle of operation of the player also reveals a weakness in the focusing mechanism. It is a feedback style motor operated system allowing for the laser lens to move up and down and in and out in order to keep the digital bit stream in focus.
At one point in time, there was a product which reduced the aperture of the lens assembly. That was interesting and it worked to varying degrees. Once I obtained ferrofluid I simply saturated the motor coils of the focus motors and that simply blew away any aperture reducing system. I do not believe any manufacturer uses ferrofluid today but it adds tremendous dynamics and significantly increased detail, simply by speeding up the focusing mechanism.
Once the focusing mechanism had been optimized, then the other tweaks like coloring the edges become much more prominent, at least audibly. I do have to warn any experimenters to experiment with an older player first. Any mistake in placement and the ferrofluid inside the lens assembly generally spells death for the laser head assembly. That silicon is not easy to flush out!
